Select the related letter-group from the given alternatives. A D G J : ? :: M…

Answer: Z W T Q

Reason: Each letter is paired with the alphabetic complement so that their positions add to 27 (for example, A (1) + Z (26) = 27). The same rule is used for both given pairs.

• Start with the first group: A, D, G, J (positions 1, 4, 7, 10).

• Find each complement so the pair sums to 27: A → Z (26), D → W (23), G → T (20), J → Q (17).

• Therefore the related group for A D G J is Z W T Q.

• As a check, the second pair M P S V maps by the same rule to N K H E (M (13) → N (14), P (16) → K (11), S (19) → H (8), V (22) → E (5)).
